Strain-Induced 2D Materials

In this chapter, different structural, electronic and magnetic properties of strained graphene nanoribbons are examined. All the calculations are performed by using density functional theory. Compressive stress along a nanoribbon's longer axis and tensile stress at the midpoint and perpendicular to the nanoribbon's plane are studied. There are remarkable changes in the structures, including the formation of nanoripples in the ribbons. The shape and size of the ribbons lead to variation in their electronic and magnetic properties. Strained nanoribbons show tunable magnetic properties that can be used for developing magnetic nano-switches.
